One way power / consistent junctions

[waxen shell]

I want to create a charging station that will charge any connected battery to 100%, and afaik this is impossible without some wizardry coding
So perhaps a nice solution would be to let us configure the relays whether to be directional,
Or maybe make the game a bit more consistent by making all junctions directional/one-way (but then add junction variants that let you merge cables) (ideal solution imo)

Convert high to low then convert low to high.

Connect your source batteries together and to your power source, then use power converter followed by junction before going to the battery you're charging.

Say you have 10 HV batteries, take power converter, connect the HV side to that battery bank, LV side to LV junction and charge your LV battery from that. For HV charging converter HV side to battery bank, lv side to another power converter then the hv side of that second converter to hv junction and charge your battery from that. The junction in that chain provides you one way flow and allows you to drain the source batteries under what you're charging rather than pulling power from the battery you're trying to charge.

The issue is the difference of charge states between the two sides of the circuit.

The 1 way works fine but the issue is that you need higher power (voltage) on the "Feed" side to overwhelm and charge the "Suck" side.

Currently converting to low voltage and back breaks that calculation across the two sides and allows you to charge the "Suck" side to full regardless of whether you have enough power on the "Feed" side or not.

In this example, Your battery bank, "Feed", would be on the left and your vehicle that needs charging, "Suck", would be on the right

It helps me by imagining them as pressurized vessels that are trying to equalize.

With all that said; I agree with your sentiment. There should be some kind of voltage multiplier/etc to replace all this glitching/workaround.

the junction+double converter is not a glitch, it’s the proper way to do it.
IRL you can only charge a battery if you give it more voltage than it outputs.
using power converters boost the voltage the same way you would do it in real life.
The suggestion asks for a single component that replaces 3 components… but I believe it is more fun to have to put all 3 component to “assemble” your voltage booster.
